simple lan to lan routing (not working)

I have created a RRAS LAN only router on windows 2008 R2

segment 1

172.16.0.0        network
172.16.16.20    gateway
255.255.0.0      subnet

segment 2

10.0.0.0        network
10.0.0.1    gateway
255.0.0.0      subnet

RRAS interface A 172.16.16.20
RRAS interface B 10.0.0.1

i installed rip 2 protocol

still client cant ping hosts on the opposite network, any idea what i may be doing wrong ?
